Cl. 137-565 1 Claim ABSTRACT OF THE DISCLOSURE In its broadest form, the invention comprises a generally cylindrically shaped housing for a submersible pump and includes a drain cover at the top with a trap and seal arrangement in connection. Various access to the housing may be obtained from floor and/or area drainways, and such access is provided by conduit to the bottom of the cylinder where the suitable submersible pump is located. An effective electrical control outlet is provided inside the building and too, there are other access conduits, as for instance, connection to drain tile and the like. Discharge is effected through interconnection with the sump pump. The purpose of invention is, of course, to avoid accumulation in critical areas such as a basement, areaways, exterior drains, irrespective of location of sewage systems. By this system, the accumulated drainage can be disposed of on the ground, to another sump or to sewage system.

To more fully appreciate the invention, reference is made to the ensuing drawings in which:

FIGURE 1 is a view in partial section showing the installation of one form of invention.

FIGURE 2 is a modification of the invention of FIG- URE 1 showing areaway drain installation with footing drain tile connection.

FIGURE 3 is a modification of the systems of FIG- URES l and 2 disposed in a basement with drain tile section and attachment to plural floor drains, or combination floor and areaway drains.

FIGURE 4 illustrates a basement installation of the invention shown in FIGURE 1 and modified for floor, stand pipe and laundry tray drainage and discharge thereof.

With especial reference to FIGURE 1, there is shown an areaway installation 100 comprising a vertical cylinder having a cover 110 which is suitable for retaining a foraminous drain section 112 as shown. The cover 110 is adapted to fit into the open upper end of the cylinder, the rim thereof lying substantially contiguous the surface of the areaway as shown. The cylinder wall 114 is connected permanently and in sealed relation to the bottom 116, said wall containing at least one aperture as at 118 to the appropriate discharge conduit 120. A related aperture 118 is indicated to accommodate the conductor connected to the control switch as shown, said conductor being the source of energization of the interiorly disposed pump. The pump, being secured in fixed relation to the bottom closure 116, is preferably of the submersible type, energizable upon submergence and inactive, otherwise. Thus, in operation, during the wet season, the pump is energized for activity as the condensate or surface seepage from the exterior of the building construction fills the cylindrical container by passage through the upper drain generally indicated within the top 110. The device is hoe adapted to preclude draining areaways into existing sewage systems, intercepting the water between the graded ex terior of the building and the basement floor thereof.

In the modification shown in FIGURE 2, the installation 200 comprises top 210 with suitable aperture 212 accommodating the drain cover, the subterranean cylinder being connected to the cover 210 and comprising sections 214 and 216, the former of which connects the areaway drainage conduit 220', and electrical conductor connection 222, as indicated as well as discharge 224.

Thus, the interceptor system 200 is adapted to accommodate both drainage from the areaway per se, and drain tile seepage from close to the foundation of domestic and related buildings, thereby relieving the basement of seepage caused by settling of fluids below the normal grade and through the foundation onto a basement floor. Obviously, by energization of the system 200, a continuous removal of drainage either from adjacent the foundation wall or from interiorly of the areaway can be effected instantaneously. It is noted that the present installation is adapted to disposal beneath the level of the basement floor, per se.

The system 300 includes removable cover 310, said cover having a drain aperture 312, the cover being secured to the cylinder at the top end to the segment 314 extending the overall cylinder length from the modification previously shown. Additionally, the modification includes an extension 316 resting intermediately of the fixed cylinder component 318, and element 314. The fixed cylinder component 318 has a sealed base .320 upon which the pump rests, and from examination it will be further noted that the respective floor and areaway drains 330 and 350 terminate adjacent the bottom of the interceptor unit. Drain tile access 360 to the interior of the system is indicated in element 316. Thus one has a. plumbing interceptor for area, foundation and floor drains, all suitable for collecting the entire in a single composite packed unit. The pump is readily available for maintenance from the inside of the house and which is designed to discharge the collected fluids from critical points in and about the foundation. The specific unit is adapted to recover condensate from air conditioning units, areaway drains and washing machine overflows. By virtue of the extensions 314 and 316, the proper grade of tile under the footing may be assured inasmuch as the overall efliciency of the unit is not impaired by such minor increases in depth of the pumping unit per se.

With especial reference to the FIGURE 4 modification, the unit is particularly adapted to discharge of the drain fluids into a sewer line, such as shown. For example, the unit comprises cover 410, cylinder 414, said cylinder including discharge access 416 and sealed bottom 418. The cover in this instance is provided with a suitable vent at 412, the condensate therefrom being recirculated to the bottom for discharge as indicated. A suitable energizing system is provided for the pump which is of a submersible on-off type energizable upon the presence of drainage at the base of the pump.

I claim:

1. A sump pump interceptor device adapted to interposition between drainage collection and disposal elements, comprising in combination:

A. at least one upright water tight pump housing, said housing being cylindrical in vertical cross-section and including closed top and bottom portions;

B. collection drainage input means comprising an integral top cover, a central portion only of which is foraminous in part;

C. a housing extension of like diametrical dimension to the housing, interposed between the said housing and the top cover, said extension defining at least one area drainage conduit access aperture on the side thereof;

D. a sump pump Within the housing and at the bottom thereof, selectively energizable and de-energizable upon inundation;

E. means connecting the pump to at least one drainage output; and

F. power means to selectively energize and de-energize the pump.
